Bricklayers Risk Assessment: Trade-Specific Guide

You've been asked for a risk assessment. Usually by a principal contractor or housing developer. Usually with a start date looming. You search for a bricklaying example and find the same generic construction template every time: slips, trips, PPE, tidy site. None of it describes your day.

Bricklaying risks are trade-specific and cumulative. Nobody wrecks their back in one dramatic lift. They wreck it over ten thousand block lifts with a twist in them. Cement dermatitis creeps up until cracked hands stop a job. Dust, vibration and noise from the disc cutter all bank up over years. A template that misses those hazards isn't worth the paper it's printed on, and an inspector will spot the gap straight away.

Why Bricklayers Need Their Own Risk Assessment

The duty comes from regulation 3(1) of the Management of Health and Safety at Work Regulations 1999: every employer makes a suitable and sufficient assessment of the risks to their workers and anyone else affected by the work. Employ five or more people and regulation 3(6) requires you to record the findings. The Health and Safety at Work etc. Act 1974 sits above it with the general duty to protect health, safety and welfare so far as reasonably practicable, and CDM 2015 regulation 15 requires contractors to plan, manage and monitor their own work. Self-employed bricklayers running their own undertaking have their own assessment duty under regulation 3(2).

Suitable and sufficient is the phrase that catches templates out. It means the assessment matches the actual task, site, people, equipment and materials. A generic site document with "bricklaying" typed in the title box fails that test, because repetition, load, posture, dust and vibration never appear in it.

I won't re-teach the five steps here. The step-by-step guide to writing a risk assessment covers the process. This guide is about what goes in the bricklaying columns. For a head start, the General Builder RAMS template is built for small firms doing exactly this work.

The Hazards a Bricklayer Risk Assessment Must Cover

Six hazards do most of the damage in this trade. Each one below gets the hazard, why it's bricklayer-specific, and the controls in the order HSE expects you to apply them.

Manual Handling of Blocks and Bricks

Block laying is one of the most repetitive handling jobs in construction. A bricklayer handles heavy units all shift long, often with a twist, a stoop or a reach. HSE guidance is clear that injuries usually come from that ongoing repetition and posture, not a one-off bad lift. Risk rises with the weight of the unit, and when laying above shoulder height or below knee height.

Start with the myth: there is no legal weight limit for bricks and blocks in the UK. The Manual Handling Operations Regulations 1992 set no weight limit anywhere. Regulation 4(1)(a) says avoid hazardous handling so far as reasonably practicable. Regulation 4(1)(b) says assess what's left, reduce the risk to the lowest level reasonably practicable, and give workers general indications, and where you reasonably can precise information, on the weight of each load and the heaviest side of any load that isn't evenly balanced.

What about two people lifting the heavy ones? HSE no longer recommends it. Earlier guidance suggested two-person lifting for blocks over 20 kg, but HSE found it hasn't proved workable on real jobs. The current answer is to specify the lightest block that meets the design specification. In most cases a block under 20 kg is available that will do the job, so talk to the designer early if the drawings call for dense units.

Controls to write down, in order:

• Specify the lightest suitable block, and cut down the use of heavier ones
• Get blocks delivered as close as possible to the point of use, on level ground
• Load out with pallet trucks, sack trucks or machines, never by hand up a ladder
• Set platforms so laying happens between chest and knee height
• Set spot boards at a comfortable height, next to you rather than behind
• Handle blocks close to the body and avoid double handling
• Wear gloves against sharp edges and mortar

Never carry blocks up ladders. It's one of the few blanket rules in HSE's block handling guidance, and it belongs in your assessment word for word.

Cement: Dermatitis and Burns

Wet cement is highly alkaline, pH 12 to 13. Trapped against the skin, it can cause a burn or ulcer that develops fast, and extreme cases have needed skin grafts. Day to day, the bigger risk is dermatitis. Cement causes irritant contact dermatitis through abrasion, and its chromate content can trigger allergic dermatitis that you don't shake off once you're sensitised. Manufacturers add an ingredient to reduce the chromate, but it only works to the shelf date. HSE names bricklayers among the trades most at risk of skin disease.

Cement is a hazardous substance under the Control of Substances Hazardous to Health Regulations 2002, so treat it as a COSHH issue, not just mess. The COSHH essentials for builders guide covers the assessment side.

Practical controls: waterproof gloves marked EN374 and tested for alkalis (class K), wellingtons for standing in wet product, waterproof trousers or knee protection when kneeling, and washing cement off the skin as soon as possible. Loose gloves that trap cement at the wrist make things worse. Welfare needs running water, soap, towels, basins big enough for forearms and an emergency eyewash. If the site has none of that, it's the first line on your assessment.

Silica Dust from Cutting

Cutting bricks, blocks and kerbs with a disc cutter throws out enormous amounts of dust containing respirable crystalline silica (RCS). Breathed in, RCS causes silicosis, COPD and lung cancer. The dust is fine enough that you can't always see it, and the damage builds quietly over years.

The numbers show why HSE treats this work as high risk. The workplace exposure limit for RCS is 0.1 mg/m3 averaged over eight hours. Uncontrolled dry cutting with a cut-off saw can hit peak exposures up to 70 mg/m3, hundreds of times the limit, within moments of starting.

Controls go in this order, and your assessment should show you worked down it:

• Limit the number of cuts at design and setting-out stage
• Use a block splitter, or get material cut off-site and delivered
• Where cutting on site can't be avoided, fit water suppression to the saw fed by a pressurised supply at around 0.5 litres per minute, or use on-tool extraction with an H or M class unit
• Wear RPE with an assigned protection factor of 20: an FFP3 disposable or a half mask with a P3 filter

Tight-fitting masks need face-fit testing, and the wearer needs to be clean shaven to get a seal. Nuisance-grade dust masks don't protect your lungs and shouldn't appear in the assessment at all.

Hand-Arm Vibration from Disc Cutters

The same saw that throws dust also shakes your hands numb. The Control of Vibration at Work Regulations 2005 set a daily exposure action value of 2.5 m/s2 A(8) and an exposure limit value of 5 m/s2 A(8). At the action value you're expected to introduce measures to reduce exposure, and the limit value should never be exceeded. Regulation 5 requires an assessment based on your actual tools and how you use them.

There's no fixed "safe minutes" figure for a disc cutter. Don't let anyone tell you there is. What HSE guidance does say is that regular use of modern, well-maintained powered tools is likely to reach the action value after about one hour of non-hammer-action use. Grinders and hand-held concrete saws are named as tools likely to push users past the action value. On some tools, an hour of cutting is all it takes.

Controls: cap and spread trigger time across the gang, rotate who cuts, keep tools maintained because worn bearings and dull blades raise vibration, and look at low-vibration models when buying or hiring. The HAVS guide for trades goes deeper on exposure maths and symptoms.

Noise from Cutting and Grinding

Angle grinding and cutting sit at an indicative 90 to 110 dB. The Control of Noise at Work Regulations 2005 set a lower exposure action value of 80 dB(A), an upper action value of 85 dB(A), and an exposure limit value of 87 dB(A). Don't confuse the limit with the action values: 87 dB(A) is the ceiling that must not be exceeded once the effect of hearing protection is accounted for, not the trigger for handing out earplugs.

You don't need a sound meter to spot the problem. The rule of thumb: if you have to shout to talk to someone two metres away, for more than about two hours a day in total, you're probably at or above 85 dB. That describes most days with a disc cutter in them.

Controls before ear defenders: cut less, cut off-site, use the splitter, and screen the cutting position away from other trades. Then hearing protection for whoever's still exposed. Bricklayers next to scabbling or chopping gangs get hit by other people's noise too, so the assessment needs to cover where trades sit relative to each other.

Scaffold Work and Loading Out

Work at height is the biggest single cause of fatal and serious injury in construction, particularly on smaller projects, and most bricklaying happens off a scaffold. The Work at Height Regulations 2005 regulation 4 requires the work to be properly planned, appropriately supervised, and carried out only when the weather doesn't jeopardise safety.

The platform itself: fully boarded, usually at least 600 mm wide, with a top guard rail at least 950 mm above the edge, a toe board, and intermediate rails so no unprotected gap exceeds 470 mm. Check boards are supported and not overhanging.

Brick guards get their own mention because they're written into assessments wrongly all the time. Brick guards stop material falling between the gaps in the guard rails. They do not stop people falling. They're used in addition to guard rails and toe boards, never instead of them. An assessment that lists brick guards as fall protection is wrong, and it reads as not understanding the equipment.

Loading out is the other trap. Scaffolds are not usually designed to take heavy loads on working platforms. If you mean to load a platform with blocks and mortar, tell whoever provides the scaffold first, because it will likely need a bespoke design. A tonne of blocks on a platform built for people and hand tools is an overload waiting to happen.

Choosing Controls: The Hierarchy Before PPE

Every section above works down the same ladder, and it's worth being explicit about it because so many assessments jump straight to the bottom rung. Avoid the risk where you can, engineer it out at source, organise the work around it, and only then reach for PPE.

The Personal Protective Equipment at Work Regulations 1992, as amended in 2022, build that ordering into regulation 4: suitable PPE must be provided where a risk remains, except where and to the extent that the risk has been adequately controlled by other, equally or more effective means. In plain English, PPE is the backstop, not the plan. Gloves don't fix a dense block specified when a lighter one would do. An FFP3 mask doesn't cancel out avoidable dry cutting.

The 2022 amendment extended these duties beyond employees to workers, which matters for small firms using labour and subbies on casual arrangements.

What Good Bricklayer Controls Look Like

The difference between a weak assessment and a usable one shows up line by line.

Notice what the good version does. It names the actual block weight, the platform arrangement, the cutting method and the trigger time. A site manager can read it and check it. An inspector can read it and see the hierarchy has been worked through.

The same trade-specific approach applies across the trades your firm touches. The risk assessments for roofers guide shows how height and fragile-surface hazards get handled, which is worth a read if you move between brickwork and roofing packages.
